HERBERT JERSTRUM, OF CHICAGO, ILLINOIS, ASSIGNOR TO HERBERT A. STREETER, OF SAME PLACE.

CIGAR-BUNCH MACHINE.

SPECIFICATION forming part of Letters Patent No. 673,124, dated April 30, 1901.

Application filed March 26, 1898. Serial No. 676,333. (No model.)

To all whom it ntay concern:

Be it known that I, HERBERT J ERSTRUM, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Cigar -Bunch Machines, of which the following is a specification.

My invention relates to improvements in cigar-bunch machines, and more particularly to improvements on the cigar-bunch machines heretofore patented to me in Letters Patent of the United States No. 528,166, of October 30,1894; No.536,630, of April 2, 1895, and No. 588,912, of August 24, 1897.

The objects of my invention are to improve and simplify the construction and operation of the machine of my said patents, to facilitate the feeding of the tobacco to the bunch forming and compressing devices, and to secure uniformity in the bunches produced by the machine.

My improvement consists in the combination, with acompressing-plunger, a charger, a movable sectional bottom for the charger, and the knives or cutters for severing the charge, of an endless flexible feeder operating to feed or convey the tobacco in a continuous stream about the width of the bunch or charger into position to be operated upon by the compressing-plunger, charger, movable sectional bottom, and knives, and comprising, essentially, a pair of endless flexible belts traveling on a pair of horizontal pulleys and provided each with a series of blocks forming the side walls of the feeder, the two belts being placed a short distance apart to give room for the tobacco between the blocks. The upper and lower loops of the endless flexible feeder pass over bed-plates, which support the tobacco or keep it in position in the endless groove or channel between the two series of blocks on the two endless belts. The lower bed-plate or tobacco-supporting part is provided with an opening for the movable sectional bottom to work up and down through, and the compressing-plunger works up and down between the upper and lower loops or portions of the endless flexible feeder, and to keep the tobacco in position at the curved portion of the endless flexible feeder, where the same passes around the pulleys, curved shoes are provided.

. My invention also consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown and described, and specified in the claims.

In the accompanying drawings, forming a part of this specification, Figure 1 is a plan view of a machine embodying my invention. Fig. 2 is a side elevation. Fig. 3 is a front elevation. Fig. 4 is a longitudinal section on the line -.L 4 of Fig. 1. Fig. 5 is an enlarged cross-section of the flexible feeder on the line 5 5 of Fig. 4. Fig. 6 is an enlarged cross-section on the line 6 6 of Fig. 4. Fig. 7 is a detail longitudinal section on the line t 4: of Fig. 1. Fig. 8 is a sectional view similar to Fig.7, showingthe parts inaditferentposition. Fig.9 is a detailsection on the line 9 9 of Fig. 6. Figs. 10, 11, and 12 are detail views, partly in section, showing the bunch-rolling mechanism.

In the drawings similar letters of reference indicate like parts throughout all the figures.

In said drawings, A represents the frame of the machine.

B is the endless flexible feeder, the same having a continuous endless channel B to receive the tobacco in a continuous endless stream and convey it to the charger, com pressing plunger, and other cooperating parts. This endless flexible feeder is preferably composed of two parallel belts b I), each provided with a series of short blocksb', secured thereto to form. the sides or walls of the tobacco-channel B. The two belts or bands I) b are placed just far enough apart to form the tobaccochannel B and which should correspond in width to the charger G.

B B are horizontal pulleys upon which the endless flexible feeder travels.

B is a tobacco-supporting plate or bedplate, over which the upper loop or parallel around the pulleys B or B serve to keep the tobacco in position between the two series of blocks 1) on the two belts b b of the endless flexible feeder, and thus to cause the tobacco to be carried around the pulleys B B in a continuous path. As the channel B for the tobacco is thus a continuous and endless one the surplus tobacco severed or sheared from the charger by the knives at each operation is or may be thus continuously kept in the feeder and redelivered into position for fornT ing a charge. In other words, the operator places the tobacco in the upper course of the feeder, and it is carried thence under shoe B and over pulley B at the left of Fig. 4. It then passes along table B to the charger,'

where the surplus, if any, is severed from the charge and left in the feeder-channel. This surplus is carried by the feeder around pulley B at the right of Fig. 4 and along the uppercourse of the channel to the starting-point, where the fresh tobacco is being added. While the tobacco is moving over plate B more tobacco may be added, if necessary, as full access to the feeder-channel is permitted while it is moving between the left pulley B and the charger.

The charger G has a horizontally-swinging movement to carry it from the charge-receiv- 'F and the rolling-table G and apron H.

ing position, where it registers and cooperates with theendless flexible feeder B, the movable sectional bottom D, a'nd the compressingplunger E, to the position where it registers and cooperates with the discharging-plunger In order to give the charger this horizontal swinging movement, it is secured to a horizontal vibrating swinging arm 0, secured to a vertical shaft G which is operated by a pinion O thereon, that engages a vibrating segment-gear The movable sectional bottom D is composed of a series of separate sections 61, mounted to reciprocate independentlyof each other in a vertical reciprocating slide or cross-head D, by which the sectional bottom as a whole is moved up and down to force a charge of tobacco from the tobacco in the feeder-channel B up into the charger O and above the reciprocating knives K K, by which the charge in the chargeris severed from the main tobacco-supply in the channel B of the feeder. Each of the movable sections d is provided with a stem d, having a collar d loose thereon and a spring CF. The slide D is moved up and down by a cam 'm. on'the cam-shaft M. The tension on each of the springs 01 is varied and regulated to force more tobacco into the charger at the central portion, so as to give the required cigar shape to the charge by a series of independently-adjustable levers D one for each section dwhich are pivoted at D to the frame and engage at their outer ends adjusting-screws D which are mounted upon a vertically-reciprocating slide D that is given the same, but a reverse, up-and-down m, similar to the cam m on the cam-shaft M. The long arms of the levers D fit under the collars d on the stems d, so that any adjustment of any lever D by the screw D bearing against the short arm increases the action of the long arm against the spring 01 The com'pressing-plnngerE has a curved or bellied under face E and is secured to reciprocating stems F. E and moves up and down in a bracket E attached to the frame. The

Wms E E are adjustably secured by screws E to a connecting-bar E The com pressingplunger E is operated by a lever E adjustably'connected by a threaded bolt E to the connecting-bar E said lever E being operated by a cam on on the cam-shaft M through a connecting-lever E and link E The knives K K are caused to reciprocate between the lower face of the charger O and theupper face of the endless flexible feeder B, and thus to sever the filled charge in the charger from the main supplyof tobacco in the feeder-channelB when the movable sectional bottom D has forced the filler charge into the charger. This will be readily understood by reference to Figs. 6 and 8. When the charger O swings horizontally to convey the charge from the charge receiving station to the charge-discharging station, the closed knives K K", in connection with the upper surface of the table A,serves to support the charge in the charger., The knife K is reciprocated horizontallyby means of a reciprocating slide or carriage K to which said knife is secured and which is moved back and forth as required by means ofa cam m on the cam-shaft M engaging rollers K on said carriage K The other knife K is reciprocated as required by a slide K, which is operated by a lever K engaging a cam m on the cam-shaft M.

The discharging-plunger F is adjustably secured by a set-screw f to a reciprocating crosshead F, mounted in suitable guides F on the frame of the machine, and is moved up and down as required by a cam m on the camshaft M through the connecting-leverF and link F The rolling-table G is preferably of a curved form, as indicated in the drawings, and is provided with a cavity g to give room for the bunching-roller O and the sag or slack h of the apronH, as will be clearly understood from Fig. 10. The rolling-table G is attached to or made integral with a movable lever G, by which the table is moved up and down to bring it into position to receive the charge, as illustrated in Fig. 10, and then in position to permit the bunching-roller O and apron H to roll the binder around the charge, as illustrated in Figs. 11 and 12. The rolling-table carrying lever G is thus operated by a cam m on the cam-shaft M. The bunching-roller O is swung or moved over the curved surface of the table G as required to cause the apron H to roll the binder about the filler charge by means of a cam m on the cam-shaft M enmovement as the slide D by meansof a cam gaging a lever 0, connected by a link 0 and spring 0 with the bent lever 0 upon which the roller 0 is mounted.

To facilitate the passage of. the continuous stream of tobacco in the feeder-channel B under the charger C, I provide a feed-roller B above the feeder-channel, and also a curved shoe B both of these parts being mounted on the stationary frame of the machine.

The endless flexible feeder B is intermittently driven by a lever T, having a roller if engaging the cam m on the shaft M, which is connected by a rod T with a lever T pivoted on the shaft of one of the pulleys B and which is furnished with a pawl T that engages a ratchet T on said pulley. The lever T is furnished with a slot t, so that its operative length may be adjusted as required to adapt the feed or forward movement of the feeder B to different lengths of cigar-bunch.
